    Abstract: Disclosed is a method for providing a public key for authenticating an integrated circuit. In the method, the integrated circuit obtains a hardware key and an integrated circuit identifier. The integrated circuit generates a derived key based on the hardware key using a key derivation function (KDF) shared with a manufacturing machine. The integrated circuit generates a private key and a corresponding public key using the derived key as an input to a deterministic function. The integrated circuit then provides the public key and the integrated circuit identifier to a partner service for authentication of the integrated circuit using an anonymized credential database to be provided to the partner service by a manufacturer.

    Abstract: Methods, systems and devices enable synchronizing obscured identification information between a wireless identity transmitter and a central server to support one-way communication of the obscured identification information to the central server. The wireless identity transmitter may be a compact device configured to broadcast messages, such as through Bluetooth® advertisements, including an obscured identifier for receipt and relay to the central server by proximate proximity broadcast receivers via sighting messages that may also include location information. The central server may decode received identification codes to identify the wireless identity transmitter. The wireless identity transmitter may create message data by concatenating identifying information with an incrementing nonce, encrypting the concatenated information, and truncating the encrypted information. Alternatively, concatenated identification information may be encrypted with a pseudo-random function and a secret key known by the central server. The central server that may compare received data to pre-calculated encrypted data.
